PS4 thumbstick extender

These are PS4 thumbstick extenders. I tried printing a few off of here, but could not get them to print properly without adjustments. So I created my own set in fusion 360. there are two versions a plain concave top and one with concave and a radioactive symbol. I printed these in PETG and PLA, both work great. I also dipped the tops in clear "flexseal" to give more grip. height is 17MM, and will raise the stick about 15mm.
